Live repository

Not pinned. Installing fetches whatever the repository holds at the time you run the command.

No human has reviewed this code. The checks below are a static scan of the files at one commit — nobody has run this skill or judged whether it works. A skill runs with whatever access you give your agent, so read the source before you install it.

Automated safety checks

scanned

This skill passed all 6 checks. We read its files at one commit and looked for the things that make a skill dangerous to run — not for whether it works.

  • Declares what it does: passed

    SKILL.md parses and declares a name and a description.

    SKILL.md exists, its frontmatter parses, and it declares a name and a description.

  • No undeclared network calls: passed

    Makes no network calls.

    Every host the skill dials — from its scripts, its config endpoints or the commands it tells the agent to run — is either well-known package and API infrastructure or declared in its own frontmatter. Links in documentation are not counted.

  • No obfuscated payloads: passed

    No encoded or obfuscated payloads.

    No base64, hex or compressed blob is decoded and then executed, and no encoded shell commands.

  • No credential access: passed

    Reads no keys, tokens, keychains or credential files.

    Neither the code nor the SKILL.md instructions read SSH keys, cloud credentials, keychains, token stores, browser cookie databases or dotfiles that hold secrets.

  • No pipe-to-shell installers: passed

    No pipe-to-shell or download-and-run installers.

    No `curl … | sh` pattern, in the code or in the instructions, that runs code fetched at run time.

  • Pinned to a commit: passed

    Scanned simhacker/moollm at 8f6d840b2f.

    The exact upstream commit SHA that was scanned is recorded, so the result refers to specific bytes.

This is a static scan, not a review. It reads the skill's files; it does not run them, and it cannot tell you whether the skill is any good or whether the code does what its description says. A skill runs with whatever access you give your agent.

About this skill

What it does

The postel skill provides a mechanism to apply Postel's Law, which states that when a new protocol is introduced, the old one should continue to function. This means an AI agent using this skill can handle older versions of data or communication formats gracefully and avoid breaking existing systems. It ensures backward compatibility in various digital interactions.

When to use it

  • Migrating Systems: When transitioning from an outdated system to a newer version, ensuring the old one remains functional is crucial.
  • Interoperability: When interacting with legacy software or services that may not support modern protocols.
  • Data Processing: To process data files generated by older systems without causing errors due to format changes.
  • API Integrations: When integrating with APIs that have undergone version updates, maintaining compatibility is essential.

Key capabilities

  • Backward Compatibility
  • Protocol Handling
  • Legacy System Support
  • Data Format Adaptation

Example prompts

  • "Process this file as if it were generated by Postel v1."
  • "Ensure the agent can still communicate with systems using older protocols."
  • "Handle this data, accounting for potential differences in format versions."

Tips & gotchas

The effectiveness of postel depends on having information about the older protocols or formats. Providing context regarding expected variations will improve its performance.
